Hello Net I now feel that I am writing the episodes in the continuing saga of Orma's KR. By 9 this AM I had added the fuel pump and this regulator type device( It seems that restricts the flow of fuel, as opposed to controlling pressure). I ran the engine and for the first time I knew that I was running rich at WOT. In fact so rich that the engine tried to quit. I found that when the pump is on, I did not get an anticipated flood of fuel. The engine seemed normal till I reached the part where I had carved a step in the needle. At that point, the engine flooded. After several trial settings, I installed the last needle that I got from Joe at Revmaster. To get the best run, I would start with the fuel off and after a warm up I would push the throttle to WOT and turn on the pump. But, the real question is what about the temp. I made a 3 minute run at WOT, controlling the flooding by moving the mixture control. I was able to hold the temp of #3 to 450. The engine was turning 3000 and 30 MP. This is the first time that I was able to see the effects of the fuel cooling the cylinder. This is still not too Kool. I need to cool the thing down at least another 50 degrees. I can live with 400 CHT on takeoff. All the time that I have had the CHT gauge in the cockpit, and I don't remember what the takeoff numbers were on the old engine. What are some of the takeoff numbers that other get?
